Featuring comprehensive digital signal processing (DSP) and remote setup via Ethernet / USB in a 2U rack-mountable, fan-cooled chassis, the AX6220Z 1000W 70/100V High-Impedance Power Amplifier from Behringer is a professional, high-performance, 2-channel power amplifier for installation with 70 / 100V distributed speaker systems. It utilizes transformer-less, class-D topology and switch-mode power technology to provide low noise and good transient response while reducing amplifier energy costs. The dual variable-speed fans create back-to-front ventilation to keep racks running cool, and zero-attack limiters combine with independent DC and thermal overload protections to safeguard the amplifiers and connected speaker systems. Featuring 24-bit / 96 kHz converters to ensure signal integrity, the processing section of this AX6220Z amplifier maintains an broad dynamic range while offering sophisticated DSP options including delay, crossover, dynamics, and both parametric (8-band) and dynamic (2-band) EQ. Parameters can be set and stored using intuitive front-panel controls and the amber backlit LCD also displays meters and indicates muting, system fault, over-current, and overdrive. Additionally, the front panel also has an illuminated master volume knob with a clipping indicator. A front-panel USB connector is included to allow setup on a local PC, while a rear-panel Ethernet connection enables remote control and monitoring using the Behringer Amp Remote software application (sold separately). Changes to settings can be prevented with secure lockout. The input channels accept balanced or unbalanced microphone or line-level signals via XLR / TRS combination jacks or 3-pin Euroblock connectors. The outputs are connected to speakers via a 4-screw terminal strip. A 2-pin Euroblock socket is also provided for sequential power control and remote power On / Off. Furthermore, this system features all mating Euroblock connectors as well as integrated rack ears and screw covers. The AX6220Z Power Amplifier represents the apex of power, flexibility, and control. It is a suitable choice for contractors designing high-performance sound reinforcement and playback systems for the most demanding applications. Whether accessed directly, from across the hall, or halfway around the planet, this amplifier features a plethora of connectivity and control options, providing immediate access to unbridled functionality.
